Cautions - Install Manjaro on Lenovo E42-80

https://www.cnblogs.com/dylanchu/p/9750760.html

1. Make USB liveCD

While making usb installing media, do not use "UltraISO", it would not work.

Use command "dd" or ‘usbwriter‘(1xx KB) under windows.

2. Enable WiFi (Only needed when kernel version < 4.18)

NOTE
For Linux with kernel version 4.18 or higher, this step is NOT needed as I have submitted a patch which has been integrated since Linux4.18-rc1 to solve this.

After setup the wlan hardware is not able to use. While execute "sudo rfkill list all" you will see

    ...
    0: hci0: ideapad_bluetooth
        Soft blocked: no
        Hard blocked: yes
    1: phy0: ideapad_wlan
        Soft blocked: no
        Hard blocked: yes
    ...

And wlan cannot be enabled. Also sudo rfkill unblock all won‘t solve that.

To solve this, you need to edit two files:

sudo vi /etc/modprobe.d/ath10k_core.conf
    --- then make sure "options ath10k_core skip_otp=n"
sudo vi /etc/modprobe.d/ideapad_laptop_blacklist.conf
    --- add line "blacklist ideapad_laptop", save and quit.

Reboot and you will find wlan and bluetooth are ready to use.
(Driver /lib/firmware/ath10k/QCA9377/hw1.0/ is already there but it‘s blocked by ideapad_laptop by default)

3. Caution on graphics card driver

Do NOT use video-vesa !

Manjaro settings manager allows you to install or uninstall hardwares‘ drivers easily via GUI. But just be aware that on lenovo E42-80 you should use the graphics card driver video-linux instead of video-vesa. Once video-vesa is installed and you reboot your pc, you‘ll find your desktop would split into two part which left and right are swithed.
